Transparent Frogs and Other Japanese Innovations

Japan, known for giving the world sushi, whose advertising slogan seems to be "you can never have too much neon," and where the world's first fuel-cell-powered robot was designed, has done it again.

Scientists in Hiroshima have developed the first transparent frog.

No joke.

Actually, it's the frogs' skin that's transparent, making it possible to observe what's going on inside without hurting the frog.

They've also got glow-in-the-dark frogs.

Again, no joke. In both cases, the frogs were developed to make medical research easier.
